Besides what Phil mentioned below, I can't write more than one record to the WAL. You're closing the file after every write, the second time you write the error `seek data/rebuf.tmp: file already closed` is returned.

I also think your rotation will delete the wrong segment when you have more than ten segments - imagine you're writing rebuf-1 to rebuf-10 - what's the "oldest file" to delete now? Besides, should you really delete those files?

Yes there are a lot of bugs since I just wrote this in one sitting today. Will be fixing all of this. For log rotation, I'll sort by the last_modified_at ts and then purge those

Your generational approach to segment numbering is fine, if you prepend enough zeros to format the files properly then you're also able to sort them correctly. etcd uses the same trick.
